Indoor Vs Outdoor

Indoor and outdoor cannabis cultivation environments produce measurably different terpene profiles in the same genetic strain. Environmental factors—light spectrum, humidity, temperature fluctuation, and UV exposure—directly influence terpene synthesis during flowering. Outdoor plants typically develop more complex terpene expression due to natural light variation and diurnal temperature swings, while indoor-controlled environments often yield more consistent, sometimes more concentrated, terpene profiles. Breeders and seed banks frequently document these variations when describing strain characteristics, noting that terpene intensity and composition can shift between growing methods. Understanding these distinctions is critical for breeding programs targeting specific aromatic or chemical profiles.

Breeders selecting for stable terpene expression must account for cultivation method in their phenotype selection and stability testing. Seed lines developed specifically for indoor or outdoor cultivation may show distinct terpene stability under their target conditions.
